MECHANISM FOR OPERATING CHURN-DASHERS.

SPECIFICATION forming part of Letters Patent No. 359,1L5, dated March8,1887.

Application filed November 11, 1886. Serial No. 218,594. (No model.)

To aZZ whom it may concern:

Be it known that l, J AMES M. FLAoK, a citizen of the United States,residing at Sharon, in the county of Cleveland and State of NorthCarolina, have invented new and useful Improvements in Mechanism forOperating Ohurn-Dashers, of which the following is a specification.

This invention has for its object to provide IO novel and simplemechanism for imparting a rotary reciprocating to-and-fro motion to thedasher of a churn; and to such end the invention consists in thefeatures of construction and combination of devices hereinafter de- 1 5,scribed and claimed, reference being made to the accompanying drawings,in which- Figure 1 is a perspective view of my improved mechanism inconnection with a churn; Fig. 2, a vertical central sectional view ofthe same, and Fig. 3 a detail plan view of the cross-head on theoperatinglever.

In order to enable those skilled in the art to make and use myinvention, I will now describe the same in detail, referring to the 2 5drawings, where- The numeral 1 indicates a supporting-base to which issecured a standard, 2, to the upper end of which is mortised the innerend of a bracket-arm, 3, while to the extreme upper 20 end is mortisedasimilarbracket-arm, 4, these arms projecting horizontally at rightangles to the standard and parallel to each other. The standard betweenthe arms is formedinto a journal, 4*, which is a circle incross-section,

5 and on this journal of the standard is loosely mounted a horizontallever, 5, having a handle, 6, and a circular orifice through which thejournal passes, thereby permitting the lever to be oscillated in ahorizontal plane on the standard between the upper and lowerbracketarms. The inner end of the lever is provided with a cross head,7, secured midway of its length to the lever and provided at its top andbottom edges, at opposite ends,with the bevels or inclines 8, wherebyone end of the lever is higher than the other end, as clearly shown inFig. 1, which construction is for a purpose hereinafter explained.

A circular shaft, 9, having a journal, 10, at

50 each end, is located in avertical plane between the outer ends of thebracketarms, the respective journals of said shaft being loosely locatedin circular orifices in the outer ends of said bracket-arms. To theupper and lower portions of the shaft 9 are respectively secured one endof straps 11, the said straps being partially wound around the shaft inreverse or opposite directions, and the uppermost strap is carried toand connected with the highest end, 12, of the cross-head, while theother strap is carried to and connected with the lowest end, 13, of thecross-head. Thus it will be seen that by the upper and lower bevelededges of the crosshead the straps, in operati0n,will not interfere witheach other, but each will operate on its 6 special part of the shaft 9when the lever is oscillated. The lower journal of the shaft 9 isextended through the lower bracketarm, and

to it is secured one end of a sleeve, 14, having an angular socket inits other end receiving the squared upper end of the dasher-rod 15,where it can be detachably secured by a pin, 16, or other device.

The dasher-rod carries cross-arms 17 and at its lower end is furnishedwith a slat having"; 5 its ends bifurcated, as at 18, the object beingto permit the bifurcations to penetrate the butter, so that the lattercan be lifted from the churn. The upper end of the dasherrod beingdetachably held in the socket of the sleeve 14 can be readily removedtherefrom and the dasher then lifted from the churn.

As the bracket-arms are nlortised on the standard by simply providingsaid arms with squared orifices fitted to correspondingly- S5 shapedparts on the standard, and as the standard itself forms the journal forthe lever between the bracket-arms, the construction is economical andreadily constructed of wood, while the sleeve will be of metal.

The lower bracket-arn1 constitutes a rest on which the lever bears inits oscillatory movements, and all the parts being separable'they can bedetached and stored away in a suitable place until required for use.

I am aware that it is not broadly new to operate the dasher-rod of achurn by straps passing from the dasher-rod to arms on a swinging leverpivoted on a standard, as in Letters Patent Nos. 240,508 and 264,598. Myconstrue I00 tion, as described and claimed, differs therefrom in alever journaled intermediate its ends on a standard and having atitsinner end a cross head located at right angles to the lever and swingingbetween the upper and lower brackets at a point between the jeurnaledpart of the lever and the outer ends of the brackets in which the shaftis j ournaled that connects with the dasher-rod. I also so bevel thesingle cross-head that one end is higher than the other end, so that thestraps move without interference with each other. The entireconstruction is simple, useful, and substantial.

Having thus described my invention, what I claim is- The combination'ofthe standard, the upper and lower bracket-arms separab] y mounted on thestandard to provide an intervening space, the leverjournaledintermediate its ends directly on the standard between the inner ends.naled at its upper and lower ends in the free ends of the bracket-arms,and the straps conneeted with the shaft and the ends of the crosshead,substantially as and for the purposes described.

In testimony whereof I have affixed my signature in presence of twowitnesses.
